tibiæ and tarsi, paler, brownish, also posterior tarsi slightly paler; 

 the hairs below the basal half of hind femora longish; bristles on hind 

 tibiæ somewhat small. Wings colourless or nearly so, thick veins 

 blackish brown, the others paler, brownish and rather fine; costa not 

 reaching to the middle, about 0,46 of the wing-length, costal divisions 

 about as 7 — 3 — 2; costal cilia long; fourth vein evenly curved, only 

 slightly more at the base. Halteres black. 



Female. Quite similar; the hairs below hind femora about as 

 in the male, 



Length 1,7 — 2 mm. 



A. egregia seems to be rare, I have only one pair which was taken 

 in copula by my wife at Brede ^U 1922 on the leaf of a linden-tree. 



This species is easily determined as it in the groiip is the sole 

 species, besides fungivora, with long costal cilia and black halteres. 

 In my table to group II it will come under 12, and here it will at once 

 be distinguished from jungivora by the black palpi and equal supra- 

 antennals, so that we get: 



12. Halteres black T 12a. 



— Halteres yellow or dusky yellow 13. 



12a. Palpi yellow or dusky yellow; sujDraantennals imequal. 30. futigivora. 



— Palpi black; supraantennals equal 30a. egregia. 



For the rest the species is, as seen, distinguished by many other 

 characters.

Male. Frons considerably broader than high, black, dull; inner 

 bristle of lower row in about the same height as the outer and a little 

 nearer to it than to the upper supraantennal ; supraantennal bristles 

 equal or nearly so, the upper a little nearer to each other than the 

 inner bristles of middle row, the lower very slightly closer together. 

 Antennæ black, of ordinary size, arista short-pubescent. Palpi yellow 

 or yellowish, of ordinary size and armature. Thorax black, very 

 slightly shining, with blackish pubescence. Mesopleura with uniform 

 bristles. Abdomen black, a little greyish, dull ; the short hairs a little 

 longer at the hind margins on the last segments. Hypopygium some- 

 what large, higher than long, black or blackish, shining above on
